Flinner, Big Prairie, Ohio, assignors to Mansfield Sanitary,Inc. Filed Sept. 27, 1967, Ser. No. 671,020 Int. Cl. F16l 41/00, 5/00U.S. Cl. 285-192 5 Claims ABSTRACT F THE DISCLOSURE The said deviceincludes a movable, cupped, ring flange mounted on -a sillcock adjacenta water pipe connection thereto, a cushion type ring gasket seated insaid cupped portion thereof, and a snap ring seated in a sillcockchannel adjacent said water pipe connection to hold said gasket inplace, the said device providing -a closure or seal for an opening in abuilding wall carrying said water pipe through said wall.

BACKGROUND Field of invention This invention relates to 4art of sanitaryplumbing systems and more particularly to the field of sillcock orfaucet installations on the outer wall of buildings connected to waterpipes from within said buildings and providing a closure or seal for theexterior end of the opening in said wall carrying said water pipes,particularly in geographical areas subject to freezing temperatures.

Description of the prior art The prior art of which we are familiar inthe plumbing field that relates to seals or closures for the wallopenings carrying water pipes to sillcock installations are of the rigidflange type located adjacent the water pipe connection and which are afixed and an integral part of the metal sillcock and having a surfacesubstantially perpendicular to the axial :alignment of the water channelof the sillcock or faucet Iadjacent the water pipe connection.

SUMMARY In contrast with the prior art in the field of plumbinginstallations of sillcocks and of outdoor faucets and the flanges usedfor sealing or closing the exterior end of the building wall openingsfor water pipes that pass through said walls and -are connected to saidsillcocks and faucets, the present invention avoids the disadvantagesfound in such art in the following respects, among others: Theadjustable flange of the present invention enables the plumber to adjustthe Aflange to the building wall outer surface, regardless of whether itis exactly vertical or whether the water pipe wall opening and/ or waterpipe therein is exactly perpendicular to the wall outer surface. Anotheradvantage is that it provides a seal for such water pipe openings thatwill prohibit the entry of insects into the building through saidopenings. Still another advantage is that it provides an insulation forsaid water pipe at the exterior surface of the wall.

Other advantages, more or less ancillary to the foregoing, will appearin the following description and the accompanying drawing of theinvention.

'IH-E DRAWING Referring to the drawing:

FIGURE 1 is a vertical sectional side view of a sillcock with an iceexpansion liner showing the adjustable flange in place.

FIGURE 2 is an enlarged cross-sectional view of the adjustable flangeshowing the flange in place on a wall surface that is not perpendicularto the longitudinal axis of the water pipe connected to a sillcock.

THE PREFERRED EMBODIMENTS The adjustable flange unit A is illustrated inFIG- URESl and 2 of the drawing in its position mounted on the sillcockB and affixed to the outer surface of a building wall. In FIGURE 1 theflange unit is in its normal position on a sillcock and in FIGURE 2 inits position where an adjustment is required to provide a seal.

The adjustable flange unit A includes a movable ring flange 10, having aring opening .11 centrally thereof, a cupped portion 12 adjacent saidring opening, a flat washer-like portion 13 surrounding said cuppedportion 12 and spaced apertures 14 in said washer-like portion 13 toreceive screws or the like, a cushion type ring gasket 15 seated in saidcupped portion 1.2 of said flange and a snap ring 16 for holding saidring gasket 15 in place. The sillcock B has a circular channel 17adjacent the outer surface of the building wall with a side wall 18adjacent the building wall and a side wall 19 remote therefrom. The saidside wall 18 having a rim diameter slightly smaller than that of sidewall 19. Also the diameter of said flange ring opening 11 preferablyshould be somewhere between the rim diameter of said channel side wall18 and that of channel side wall 19 for e-ase of mounting said flange 10in said sillcock channel 17 and for ease in adjusting it to an irregularwall surface.

The adjustable flange unit A is mounted on said sillcock B with theinner surface of the cupped portion 12 faced toward the building wall.Prior to such mounting the cushion type ring gasket 15 may be seated insaid cupped portion 12 and then the side wall 18 of the channel may beinserted through the ring opening 11 of the flange 10. Thereafter, thesnap ring 16 is seated behind the ring gasket 15 in the channel 17adjacent said side wall 18 thereof. Said adjustable flange unit A maythen be affixed to the building wall by means, such as screws 20inserted through the rim apertures 14.

What is claimed is:

1. A sillcock and an adjustable flange Iassembly therefor of the classdescribed comprising:

(a) a sillcock having a substantially cylindrical tubular portionthereof adjacent a water pipe connection thereto, said portion providedwith flange holding means thereon, said flange holding means beingdefined by radially extending flanges secured to and spaced apart alongsaid tubular portion,

(b) -an adjustable flange assembly having scalable elements for waterpipe wall openings movably mounted on said sillcock flange holding meanscomprising,

a ring flange having an inner diameter larger than the outer diameter ofthe tubular portion located between said radially extending flanges,

a cushion type ring gasket, and

an annular retaining means therefor having an inner diametersubstantially equal to the outer diameter of the tubular portion locatedbetween said radially extending flanges.

2. The sillcock and adjustable flange assembly defined n claim 1,wherein the ring flange has a cupped portion ladjacent the ring openingto receive and provide |a seat for the cushion type ring gasket.

3. The sillcock and adjustable flange assembly therefor defined in claim1, wherein the ring flange has apertures adjacent the periphery thereofto receive means for securing the ring flange to a building wall.

4. The sillcock and adjustable flange assembly therefor defined in claim1, wherein the annular retaining means is -a snap ring.

3 4 5. The sillcock adjustable ange assembly defined in 2,404,539 7/1946 Schmidt 285-192 claim 1, wherein the ring ange has a cupped portion2,767,564 11/ 1956 Green 285-231 X adjacent the ring opening to receiveand provide a seat 3,224,793 12/ 1965 Benjamin 285-321X for the cushiontype ring gasket 'and the annular retain- 3,226,136 12/1965 Braden285-192 X ing means is a snap ring. 5
